As a part of Memphis’ North Mud Island Interceptor Sewers Project, Stiver Engineering was retained to provide a shoring design for sliplining an existing 120” diameter RCP sewer line with a 110” diameter Hobas pipe.
A custom trench box was proposed with an arch spreader and walers to resist the lateral pressures from weak sandy soils adjacent to the Mississippi River.
Apart from the shoring design, additional cable and rigging calculations were performed for a fall restraint safety line system.
